Title: Control-valve for a fluid operated device such as a torque converter lock-up clutch
IPC: F16H61/14
Filed: 1976-02-10
Abstract: 1483032 Change speed control CATERPILLAR TRACTOR CO 10 Feb 1976 [23 June 1975] 05103/76 Heading F2D A control valve 11 for supplying fluid pressure 21 to a line 39 for engaging a lock-up clutch 37 in parallel with an hydrodynamic torque converter 13, driving a vehicle through a planetary change-speed gear 17 having fluid-pressure engaged ratio-establishing friction clutches and brakes 18a ... 18g supplied with pressure fluid through a control valve 19, responds to first and second signal pressures 44, 46, the first, 44, output speed responsive from a governor 41, the second, 46, present in all ratios except first, reverse and neutral, whereby the lock-up clutch 37 is engaged only in the higher ratios and then only above a predetermined speed, and is released at all speeds in first, reverse and neutral, and also during all gear shifts, the valve comprising three spools, as follows, to produce snap action in both directions and hysteresis. A control spool 64, on the right, is shifted from a leftward position, shown, in which it exhausts the clutch line 39 at 52, to a rightward position, supplying thereto line pressure 21, reduced at 43, by a load spool 69, which remains in its leftward position, shown, at all speeds when, as in first ratio, reverse and neutral, no pressure exists in a ratio signal line 46. In all the remaining ratios one or other of two friction devices 18b, 18c is pressurized, which, through a shuttle valve 47, pressurizes the ratio signal line 46 to shift both spools 69, 64 towards the right, but not enough to pressurize the clutch line 39, further movement of the load spool 69 being arrested by a shoulder 72 on that spool. In this position governor pressure 44 is admitted through a radial port 74 in, and to an interior bore of, the load spool 69, where it acts rightwards on an inner third spool 79, and thence on the control spool 64 in opposition to a spring 67, which latter, at a predetermined speed, it overcomes, to cause the control spool 64 to resume rightward movement, during which exhaust communication from 59 through an axial spool bore 83 to a larger diameter radial shoulder 81 of the inner spool 79 is cut-off, and governor pressure 44 supplied thereto through a groove 78, whereupon the inner spool 79 and control spool 64 make a rapid final movement to the extreme right, fully pressurizing the clutch line 39. Reduction in governor pressure produces a similar snap action for clutch pressure release, with hysteresis, Fig. 4, not shown. During a ratio shift the transient loss of ratio signal pressure 46 produces temporary release of lockup clutch pressure 39 by releasing the load spool 69.

Title: Preparation of diborane
IPC: C01B6/10
Filed: 1946-02-21
Abstract: Diborane is prepared by reacting an alkali metal hydride and a boron tri-halide in the substantial absence of oxygen.  The hydride may be finely-divided hydride of lithium, or sodium, and the halide of boron may be BF3, BCl3, BBr3, or Bl3.  The reaction may be effected with stoichiometric proportions, or with excess boron halide, and should be carried out in the presence of an organic solvent for the halide, e.g. diethyl ether, dimethyl ether, dibutyl ether, or dioxane.  The halide may be dissolved in the solvent before introduction into the reactor, and where an ether is used, a co-ordination compound of the halide with the ether may be formed.  The reaction may be carried out in a reactor provided with an agitator and reflux condenser at 50-100 DEG  C., preferably 60 DEG  C., by use of an oil bath.  The reactor may be flushed with nitrogen, helium, neon, or argon, to ensure absence of air, and a slow stream of nitrogen may remove the B2H6 which is condensed by cooling with liquid nitrogen.  In examples, the reaction is also effected in a sealed evacuated tube, which is rotated, and contains steel balls.

The memory shown in Fig. 3 contains four sets of groups of cores, each set being of the type shown in Fig. 2 and comprising G1 . . . Gm groups of cores and D1 . . . Dx word defining wires common to all the groups. In order to read out that word defined by the association of the wire Dx and the group Gm a pulse is applied simultaneously to the wire Dx and the read wire Rm associated with group Gm. Since each pulse is such that it will not on its own change the magnetic state of any of the cores only those cores in group Gm which are threaded by both wires Dx, Rm are able to change their magnetic state inducing pulses in the associated digit wires 2. The cores are reset by applying a suitable pulse to read-wire Rm. Each of the sets of groups of cores in Fig. 3 has its own word defining wires D and each of the read wires R is associated with one group of each set. Digit wires 2 are common to all the groups of the memory. Figs. 4, 5 (not shown), illustrate systems for driving the read wires and the wires D using diode gates.
